1 Product Overview
1.1 Product Introduction
The DS310 sensor is a wireless vibration and
temperature sensor, which is used for condition
monitoring of rotating dynamic equipment in
industrial fields. This wireless sensor is powered
by a battery, can collect vibration/temperature
data in three axial directions, connects to the
gateway via Bluetooth, and uploads the monitored
data to the gateway.

4 Installation and Operation
4.1 Confirmation of the Number and
Location of Monitoring Points
Open the DHMSCare APP, click on the added
target monitoring device, and determine the
number of monitoring points (i.e., the number of
sensors) and their locations (i.e., the installation
positions of the sensors) according to the guidance
on the APP page.

4.2 Placing the Sensor
Read the following installation precautions:
4.2.1 The sensor should be installed close to the
bearing (note to avoid installing it at the fan
outlet);
4.2.2 The installation position on the equipment
casing must be clean and flat, without grease, dust,
and so on;
4.2.3 The "Y-axis" of the sensor is parallel to the
axial direction of the equipment, and the "Z-axis"
of the sensor is perpendicular to the axial
direction of the equipment.

4.2.4 The communication signal between the
sensor and the gateway is optimal when the top
surface of the sensor (the side with the LOGO)
faces the gateway.

4.3 Installation and Fixation
4.3.1 After determining the installation position
and direction, apply glue (Loctite 454 is
recommended) evenly to the bottom case. Ensure
the glue layer is not too thick (less than 2mm).
Apply the glue to the area marked red in the
figure below, covering approximately 60% of the
bottom surface.
4.3.2 After applying the glue, press the sensor
onto the designated position. Release your hand
after the glue has initially set (the initial setting
time varies depending on the type of glue. For
example, Loctite 454 glue takes approximately
Front
(logo side)
Back
5-20 seconds).
4.4 Monitoring Point Binding
Open the DHMSCare APP, Then follow the APP
prompts to complete the binding of the sensor.
Note: After binding, the sensor will
automatically search for nearby gateways to
connect to the network, and no other
operations are required.
5 Judgment of Bluetooth Signal
Strength at the Sensor Installation
Position
The mobile APP allows checking the Bluetooth
signal strength reported by the sensor to evaluate
the quality of the Bluetooth signal at the
installation location.
